Abstract

A method for producing a stator for an electrical machine, the stator having a substantially hollow-cylindrical stator core, which has a plurality of grooves spaced apart in a circumferential direction, the method including: providing at least one strip-shaped winding unit having a first winding conductor with a plurality of groove portions running straight in a transverse direction that are mutually parallel; fastening a first end of the winding unit to a lateral surface of a mandrel; winding the winding unit onto the mandrel such that it is bent around the lateral surface of the mandrel spirally; inserting the mandrel, together with the winding unit, into a cavity in the stator core; and unwinding the winding unit from the mandrel with the groove portions of the winding unit being inserted into the grooves of the stator core.
